About Me

John Rogers: I was basically raised in an automotive shop. Spent my youth testing and sometimes "breaking" automotive electronics. Ran my family's shop for awhile then spent 11 years on a national diagnostic hotline. Then started my own mobile automotive diagnostic service. I service professional automotive shops only, helping shop owners be more profitable.
